To oZ- concave) .39 o no wn that l, CARL U. BURTON, e c1512 n of the United Steies, residing at Dulu in the county of Saint Lowe and ,rically operated sending device for use in conneciion with the sendrsils upon whlch wheeled vehicles mole": of the present application has hown generally described in my atent, No. 1,383,286, issued July 5, l I automatic bridge control. In that scene is has been shown as used to sand CON (1: w 6'? od'jecent the wheels of an ore or cool rides; While it is particularly adapted to than use, it is capable of use'in connection with any wheeledvehicle.

ln connecio'ion with senders as used upon various types of vehicles, it is often most necessary "so use the send in freezing weather when the rails become slippery with ice. At such times, if there is any dampness in the send, the send tends to freeze in the send reservoir and hence does not flow.

It is an objecc of the present invention to provide s track sender which is adapted for dis'teni control and which is provided with o pcsiiively opening" and closing valve,

It is further object to provide a device or" this character in which the valve is electrically operated.

. ii is an additional object to provide/e device in which means are provided for pre-' venting the freezing of the send.

Other and further objects will appear as the description proceeds.

Broadly, my invention comprises a sand hopper or reservoir having its lower surface sloping toward a discharge opening which discharge opening is controlled by a positively operated valve. In the preferred form, "(this valve is operated by means of e solenoid end is adepied for distant control. The reservoir is provided with heaping means which, in the preferred form, consist of electric heating elements extending down throughout approximately the full depth of the recepiemiiev invention relates to e news-end im- 1 have illustrated e preferred embodiment oi my invention in the accompanying drewin s, in which- Jigure 1 is e side elevation of she complete creel: sender iy;

Figu e 2 is e view of Figure 1 es from Figure 8 is e ver 'sicel section showing the interior meohenisni oi. the sender;

Figure 1 is u plan view of Figure 3 with she cover removed; Figure 5 is e view :telren on line 5--5 of Figure 3.

E neierring now particularly as Figures l and 2, the sender container 7 is shown supported upon ihefreme 8, The container is provided with the cover 9 end with the dis charge pipe 10 leading downwardly from the conteinen, is bes a shown in Figure 2, the pipe 10 is divided into two branches 11 which discharge upon she rails 12 adjacent the wheels 13; The pcreiculer construction shown is that in use upon the ore bridge disclosed in my prior patent above referred to.

Referring now io Figures-3 to 5, the valve seei is is secured to the inner side of the bottom 15 of the coniuiner 7. The pipe 10 passes through the bo'teom of the container and, as shown, is threaded into the valve seat member 14:. Secured to end supporied by the member is is she send directing cone 16, whichi orms on inner bottom upon which the body of send'rests. The support bracket I? is secured inside the container edjecens its upper end. This bracket supports the solenoid case 18 which contains e solenoid coil 19, the coil being'protected by the cover 20. The inner central portion oi this cover 20 is formed with a conical seat or socket 21.

The tubular plunger guide 22 is secured to the solenoid case 18 in alignment with the socket 21 end with the valve seat 14. The I valve closure 23 is loceied 1n the lower end of the plunger guide 22 end is adapted to fully close the opening through she valve seal; 1%. This closure 23 is connected by rod 24: to the plunger 25, the upper end of which is adopted to fit into the socket 21 in the cover 520. The plunger 9 5 is iorined of soft steel end is adopted to he operated upon by the solenoid 19, and when so operated upon, to lift upwardly the rod 524 and thus to un sees she velveclosure 23. It will be 0bave-i served that there is a clearance between the lower end of the guide member 22 and the side of the solenoid casing 18.

cone 16 such as to permit the sand to flow out through the member 14 when the closure 23'is raised.

The heating'elements 26 have their lower ends support-ed by brackets 27, which brackets are secured to the cone 16 and valve seat member 14. The upper ends of these heating elements are secured at 28 upon the outer Suitable wires 29 lead out from the upper points of connection of the heating elements and serve to conduct the current necessary to beat them. The solenoid operating current is carried by wires 30 shown in Figure 4.

As best shown in Figure 4, the bracket 17 comprises a plurality of inwardly extending lugs 31 which serve to support. the solenoid casing 18. Intermediate these lugs 31 are open spaces 32 through which sand is introduced into thesand hopper or reservoir.

In the use of my sander, sand is placed in the reservoir by removing'the cover 9 and pouring the sand in. The solenoid is fully protected by its casing and cover and the sand passes through the openings 32 until supported in the cone 16. The sand is prevented from clogging above the valve closure 23 by the tubular guide 22. The heat supplied by the heating element 26 prevents any freezing of the sand due to dampness contained therein. r

In the operation of the sander, current is supplied to the solenoid 19 and this current causes the plunger 25 to be drawn upwardly until its upper end contacts with the seat 21. When in this position, the valve closure 23 is clear of its seat and sand flows out the lower opening and down through the pipe 10. The clearance between the lower end of the plunger guide 22 and the valve opening is made such asvto permit the desired flow of sand. When it is desired to cut oi? the flow of sand, the current in the solenoid in a r i 1,425,575.

thrown off and the plungerfand valve closure assembly drop by gravity until the clo in manufacture. It is positive in its operation and may be operated and controlled from any desired point, however distant from the location of the sand-reservoir.

The form of construction shown isto be understood tov be illustrative only as Icon template such changes and variations as "come within the. scope of the, appended claims. i
